Cramping recipes

I am looking for a cramping recipe. I am not looking for a quick to release or pain inducing enema. I only want to experience the convulsing of my intestines. I actually found a recipe on this site and for the life of me, I can't find it again.

Ideas?

Try a milk and molasses enema. 1 1/2 quarts milk and a jar of molasses. Heat the milk and stir in the molasses. You will get a quick expulsion and cramps. Gas pains and farting may last for hours.

After a good flushing clean out try this: Put 6 Dulcolax tablets into a shot glass with a half teaspoonful of baking soda and fill it with hot water. Let it sit until the tablets disintegrate then add them to two quarts of warm water. Insert a colon tube as far as you comfortably can, into the transverse is good, into the ascending is better then run in the two quarts rapidly. Remember, the Dulcolax will kick in as soon as it gets into you. Remove the colon tube and await results!
